First, we convert the VMware avi (VMnc format) to the Microsoft avi format. Next, we convert the Microsoft avi format to FLV format.

Use it like this below:
vnstat -u -i interface forces a database update for interface or creates the database if it doesn't exist. This is
usually the first command used after a fresh install.
vnstat -u -i interface --nick nick gives interface the nickname nick and that information will be later included
with queries.
vnstat -u -r --disable -i interface resets the internal counters of interface and disables it from being updated
before enabled again with the --enable parameter. This feature is especially useful for interfaces like ppp0 that
aren't always active.
And one of out put will be below,
sudo /usr/bin/vnstat -l
Monitoring ppp0... (press CTRL-C to stop)

It has got the power of vmstat,iostat,mpstat,df,free and sar.Instead of firing each single command separately ,one can fire one single command to get all the info at once.But there is a way to get the individual information too. Please see the man page . You can get it from here : http://dag.wieers.com/home-made/dstat/Show Sample Output

The unlock command for KDE 4.3 has changed from krunner_lock, this process doesn't exist anymore. So here's the update :-)

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.
That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and
voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted
to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning,
there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
